Functions

func IsPublicIP

func IsPublicIP(ip string) bool

IsPublicIP ...

tcp/ip协议中，专门保留了三个IP地址区域作为私有地址，其地址范围如下： 10.0.0.0/8：10.0.0.0～10.255.255.255 172.16.0.0/12：172.16.0.0～172.31.255.255 192.168.0.0/16：192.168.0.0～192.168.255.255

func LocalIPv4s

func LocalIPv4s() ([]string, error)

LocalIPv4s ... LocalIPs return all non-loopback IPv4 addresses
